Radius arm trick?

Radius arm trick?
I was wondering if you guys know any tricks to getting the rear radius arm off? I have it down to the front bushing (picture below), but it's stuck on. Thus far I've tried wedging a pickle fork in there and jumping on it (no dice) and pulling/rotating it with Heman strength (also fail). I sprayed on some liquid wrench and I'm letting it sit for a couple hours, then I'll retry. Just wondering if maybe there's a special trick to it that I'm not aware of?
Thanks!
Thanks!

Matjohns,
I just redid my rear diff/brakes/etc and had to remove the trailing arms to remove the whole rear diff. I used a tool that I read about on the tech tips site of Jaguar Specialties and it worked great. To learn about this tip on how to remove the trailing arm, google Jaguar Specialties and go to Tech tips, go to I believe Tip #11 and read the tip. It helped me alot and the trailing arms came off without much work at all. The one side just popped off and the other side I had to use a hammer, but it only took about 2 hits and the arm popped off. Good luck

I have a long barrel air hammer and a small diameter flat ended hammer bit that fits into the bushing hole. I soak the area with penetrating oil and a few seconds of 'air hammering' straight into the hole while prying down on the edge and the arm pops off.
Don't use a punch or small bit that will damage the bolt hole.
A short barrel hammer might work but they don't hit as hard as a long barrel.

Well, I finally figured it out. I ended up having to cut the rubber and pulling the arm off, then heating/hammering/prying the inner part bushing until it popped off (not an easy task). If you follow this method, I highly recommend grinding the rubber completely off before you commence heating with a propane torch. Ancient rubber impregnated w/ thirty years of road tar and engine oil burns REALLY good. And, since it's three inches away from your fuel line, you can see how that might go bad. But alls well that ends well! Thanks for the tips and info, couldn't have done it without ya'll.

radius arm removal trick
thanks to all posts on this; I today combined the hook tool idea with the pry bar idea.
The essential thing is to get the force applied to the INNER cup, NOT the outer, because on the outer most of the force you apply will be absorbed by the rubber.Thanks to the hook tool photo I realised that the inner cup is hollow and can receive the square end of a 12 inch 1/2 inch extension bar at an angle which has the same effect as the hook tool. Then jack up the other end of the bar with a trolley jack , wearing gloves, keeping clear and protecting your vitals such as wallet, and eyes. The car body will lift adding to the separation force. 30 seconds later POP ! free

i kind of cheated , seeing as how mu rubbers were bad anyway i put pressure on them with a crowbar just enough to stretch them some them sliced nearly all the way around & through with a stanley knife - then help constant pressure on the crow bar untill the gradually tear off . npow with a combination an angle grinders & die grinders i will carefuly slice the inside bush & expand it with a chisel whack & it'll pop off ok
